I meant that my set-up is the same in that I have similar data in those two files. This is what /etc/hosts looks like: [root@tadmin01 etc]# cat /etc/hosts 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 xxx.xxx.xxx.xxx tadmin01.zedat.fu-berlin.de xxx.xxx.xxx.xxx tadmin02.zedat.fu-berlin.de 10.141.235.254 tadmin01.test.cluster tadmin01 10.141.235.253 tadmin02.test.cluster tadmin02 It is the same on tadmin01 and tadmin02. And for /etc/sysconfig/network on tadmin01 I have [root@tadmin01 ~]# cat /etc/sysconfig/network # Generated from an ansible template NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=tadmin01 GATEWAY=xxx.xxx.xxx.xxx and on tadmin02 [root@tadmin02 ~]# cat /etc/sysconfig/network # Generated from an ansible template NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=tadmin02 GATEWAY=xxx.xxx.xxx.xxx [snip (64 lines)] I still get [root@tadmin01 ~]# hostname tadmin01 and [root@tadmin02 ~]# hostname tadmin02.test.cluster Cheers, Loris -- This signature is currently under construction.
